I have two upcoming presentations on Silverlight 4 with WCF RIA Services. The First is at Nova Code Camp on June 12, 2010 http://novacodecamp.org/.  The next one will be on June 15, 2010 at the Capital Area .Net User Group Silverlight Special Interest Group http://www.caparea.net/Default.aspx?alias=www.caparea.net/silverlight.

This is my fourth MIX conference, missing the first one. This is the first sold out MIX. The excitement is all due to the Window Phone announcement.  

The day started out as all MIX conferences (actually all conferences) does with the keynote. Scott Gu gave the first day keynote as he has done in all of the MIX conferences I have been at. His first bit of news was SilverLight 4 RC is now available. The best part of this announcement was that we can build SilverLight 4 applications with Visual Studio 2010 RC. This was not a surprise but what I had expected and would have been disappoint if not been release today.

But the star of the keynote was Windows Phone. They demonstrated the new platform; the ease of building compelling applications. This platform uses silverLight and/or the XNA framework. They showed how you can build an application that runs on the PC, Zune, Xbox and the new Windows Phone platform. The real beauty of this is that any .Net developer can start doing this today. Of course the tools for Windows Phone development are available now.

My session of the day was “Beyond File | New Company: From Cheesy Sample to Social Platform”. In the session they took the “NerdDinner” ASP.Net MVC sample and changed it to a more compelling application using iCal, Open Auth, Odata, bolg flairs, etc. Look at the code at http://www.codeplex.com/site/search?projectSearchText=nerddinner.

My last session of the day was “Understanding the Model-View-ViewModel Pattern”. This session did give me a better understanding of the MVVM pattern. The speaker had created a framework to help with creating MVVM applications. He talks about how this pattern is good for SilverLight applications. His focus was building the view part of the application in Blend.

It has been a while since I blogged. My life has been such a whirlwind since PDC09. I took 2 family vacations, one to Disney World and another to Vero Beach, and of course, there was Thanksgiving and Christmas.  To top it off, we had a lot of snow in Northern Virginia. For now,  I am trying to blog regularly again.

This week, I will be preparing for MIX10 in Vegas. This is the 5^th MIX conference (I missed the first one). At my first MIX conference, MIX07, they introduced Silverlight 1.0. At MIX08 they introduced Silverlight 2.0. At MIX09 they introduced Silverlight 3.0. Last year after MIX09, I would have thought that at MIX10 they would introduce Silverlight 4.0; however they did that at PDC09 (which I consider the highlight of PDC).

This year, there seems to be a lot more buzz on twitter about MIX than last year, which I believe has to do with Windows Phone. My focus this year will be Silverlight 4, WCF RIA services, OData, MVVM, and of course, Windows Phone. The Windows Phone sessions include programing with Silverlight and the XNA framework which should be interesting (The XNA framework is used for programing games on the Xbox). To prepare myself for the conference I have been following “Countdown to MIX10” on channel 9 along with Silverlight TV and getting up to speed on WCF RIA Services.

While I am at MIX10, I will be tweeting from the keynotes and blogging my day like I did at PDC09. You can follow me on twitter at http://twitter.com/lvanlowe . MIX10 should be very exciting.

This is the last day of PDC09. There is no keynote today and I have nothing schedule for the first session (this is the only time slot for this conference I had nothing planned). I decided this would be a good time to start playing with the new technologies I have been seeing the last couple of days. I have downloaded Windows Azure Tools for Microsoft Visual Studio (November 2009) before I left my hotel room. I was planning to work with it in Windows Virtual PC. Then I realize I have not created one with Windows 7 and Visual Studio 2010, this will take me a while to set up; so Azure will have to wait until I get home. I had also downloaded everything for Silverlight 4 development. I have an XP virtual image with Visual Studio 2010 which I started installing on the software on. Once that was completed the Silverlight 4 setup, it was time for the next session.

For the second session of the day I had scheduled “What’s New for Windows Communication Foundation 4”. I decided not to go to that session, but to do some HOL (hands-on-labs) instead. While on way to the HOL’s, I saw a great demonstration at the Live Labs product team’s booth on Pivot. I got information on how to start using this technology; another thing to try when I get home. I then started working on the “Develop Visually Engaging Applications with Bing Maps Silverlight Control” (HOL). This was a great lab it showed me that it is easy to incorporate this technology in a silverlight page. It did have some trouble with the developer code, but it told me how to get one I will do this when I get home. I am planning to do a talk on Silverlight with DotNetNuke (DNN) for the C-DUG, I believe I will incorporate this in to my presentation.

The Next three sessions of the day are for me the most interesting ones of PDC09, since my area of focus currently is developing business applications with Silverlight. These sessions are “Building Amazing Business Applications with Microsoft Silverlight and Microsoft .NET RIA Services”, “Developing Testable Silverlight Applications” and “Mastering Microsoft .NET RIA Services” will help me do this. .Net RIA service was introduced at MIX09. At MIX09,  I missed Brad Abrams session but went to Nikhil Kothari session. For me “.NET RIA Services” was highlight of MIX09.

Therefore next session I went to was “Building Amazing Business Applications with Microsoft Silverlight and Microsoft .NET RIA Services” presented by Brad Abrams. Since MIX09, I have watch Brad’s presentation many times and follow his blog, These resources has helped the most with the web application I am developing for Prince Williams Special Olympics. He covered some of the new features on what now is called WCF RIA Services and Silverlight4; such as the data binding picker, increase support for converters, “connect-the-dots’ data binding, improved validation support.

Today, I decided to go to a lunch session on “Developing Testable Silverlight Applications”. I arrived late, because I decided to eat lunch first. This was a good talk, will have to see this session again online. They demonstrated using the MVVM pattern and the Silverlight Unit Test Framework which will be very helpful to me with the application I am developing.

My next session of the day was “Mastering Microsoft .NET RIA Services” which was great follow-up to the Brad Abram session. They talk about that while “RIA services” is now for Silverlight, but there are future plans for it to be use with ASP.NET AJAX and ASP.NET Web Forms among other technologies.  This session demonstrated how the “unit of work” gets done in “RIA services”. This session also demonstrated how to do authorization. This was my last session of PDC09,

I decided not to go to “Unleashing the Power of Excel on the Web” session which was on my schedule for the last timeslot at PDC09.  This was a great PDC.

At the keynote; Steven Sinofsky talked about delivering Windows 7 to the marketplace. Then he talked about what’s coming next in IE9 and how IE is working on improving their ACID test scores. He then announce that all a PDC09 attendees will be receiving a brand new Acer laptop with Windows 7 64 bit; 2 gb of memory; with touch hardware (set up for developers).

Now Scott Guthrie, takes the stage. He announces Silverlight 4 beta is available for download. He shows some of the new features. They also added new sessions to show off the new features in Silverlight 4(there goes my perfectly planned schedule). Also .Net RIA Services (one of my favorite technologies) has been renamed WCF RIA Services.

Kurt DelBene then takes the stage and announces Office 2010 public beta and Sharepoint 2010 public beta is available for download.

As I planned I went to the Microsoft Silverlight 4 Overview; it was renamed because of the Silverlight 4 announcement.  They demonstrated the new features in Silverlight 4 such as Webcam support; printing support; the ability to build context menus and the addition of Rich TextBlock.

I was planning to go to a lunch session today; however it was canceled. In fact, I had planned two sessions on office today both have been canceled. It was just as well since there are 3 new Silverlight 4 sessions I now need to consider. Picked up t-shirts for the product teams and again looked at the HOL (Hands-on-labs).

For the next session I had 3 sessions on my schedule; the canceled office session; “ADO.NET Data Services: What’s New with the RESTful Data Services Framework”; “What’s New in Microsoft ASP.NET 4 Web Forms and Dynamic Data”. I choose the new session “Building Line of Business Applications with Microsoft Silverlight 4”. I saw demonstrated the data source window for the datagrid; VS2010 increase XMAL support including binding UI;  setting string formatting in the XMAL binding; binding to a command and a new interface for validation. There was more.

For the next timeslot; I had two sessions on my schedule “Microsoft AJAX Library, jQuery, and Microsoft Visual Studio 2010” and “Networking and Web Services in Microsoft Silverlight”. They had also added the new session “Improving and Extending the Sandbox with Microsoft Silverlight 4’. I decided to go to the networking session, because it is more in line with the application I am working on. I saw demonstrations on the improvements in RIA services; the new ClientHTTP networking stack and the TCP support now in Silverlight. Also the client policy files now have a template in VS2010.

For the last session I had “Microsoft ASP.NET MVC 2: The New Stuff” on my schedule; I however decided to go to the (HOL).  But before I went to the HOL; I picked up my new laptop. I then went to the HOL on Entity Framework 4; I will be using this stuff on my next project. I did not finish it, but it was great.

This was a great day. (new free laptop)
